Abstract

This paper considers the feasibility of different technologies for an
electromagnetic launcher to assist civil aircraft take-off. This method
is investigated to reduce the power required from the engines during
initial acceleration. Assisted launch has the potential of reducing the
required runway length, reducing noise near airports and improving
overall aircraft efficiency through reducing engine thrust requirements.
The research compares two possible linear motor topologies which may be
efficaciously used for this application. The comparison is made on
results from both analytical and finite element analysis (FEA).

Abstract

The proposed paper discusses the design and characterization of a soft
miniature Magneto-Rheological (MR) shock absorber. In particular, the
final application considered for the insertion of the designed devices
is a controllable variable stiffness sole for patients with foot
neuropathy. Such application imposes particularly challenging
constraints in terms of miniaturization (cross-sectional area ≤ 1.5 cm2,
height ≤ 25 mm) and high sustainable loads (normal loads up to 60 N and
shear stresses at the foot/device interface up to 80 kPa) while ensuring
moderate to low level of power consumption. Initial design
considerations are done to introduce and justify the chosen novel
configuration of soft shock absorber embedding a MR valve as the core
control element. Successively, the dimensioning of two different MR
valves typologies is discussed. In particular, for each configuration
two design scenarios are evaluated and consequently two sets of valves
satisfying different specifications are manufactured. The obtained
prototypes result in miniature modules (external diam. ≤ 15 mm, overall
height ≤ 30 mm) with low power consumption (from a minimum of 63 mW to a
max. of 110 mW) and able to sustain a load up to 65 N. Finally,
experimental sessions are performed to test the behaviour of the
realized shock absorbers and results are presented.

Abstract

This paper presents a numerical modeling method for AC losses in highly
dynamic linear actuators with high temperature superconducting (HTS)
tapes. The AC losses and generated force of two actuators, with
different placement of the cryostats, are compared. In these actuators,
the main loss component in the superconducting tapes are hysteresis
losses, which result from both the non-sinusoidal phase currents and
movement of the permanent magnets. The modeling method, based on the
H-formulation of the magnetic fields, takes into account permanent
magnetization and movement of permanent magnets. Calculated losses as
function of the peak phase current of both superconducting actuators are
compared to those of an equivalent non-cryogenic actuator.

Abstract

It has been proposed that a novel maglev transport system uses both of
the attractive force and thrust force of the Linear Induction Motor
(LIM). In our proposal, these two forces will be controlled by two
different frequency components. One of the frequency components is
synchronous with the motor speed (fm). Another frequency component is
drive frequency (fd). Our proposed system enables the independent and
simultaneous control of the attractive and thrust force of LIM. Each
value of the attractive and the thrust force generated by fm and fd must
be identified in order to design that LIM control system. For these
purpose, a disc-shaped LIM has been developed as an experimental
equipment. The force profiles, especially around zero slip, have been
analyzed under experimental conditions.

Abstract

The free piston linear generator is a new range extender concept for the
application in a full electric vehicle. The free piston engine driven
linear generators can achieve high efficiency at part and full load
which is suitable for the range extender application. This paper
presents requirements for designing a linear generator deduced from a
basic analysis of a free piston linear generator.

Abstract

In this paper a cross-shaped isolator consisting of cuboidal magnets
and a cylindrical isolator are compared by resonance frequency to volume
ratio and shape. Both isolators are capable of obtaining a low resonance
frequency, i.e. 0.15 Hz and 0.01 Hz for the cross and cylinder,
respectively. The volume of both isolators is comparable, only the shape
is different, resulting in a tall structure with a small footprint for
the cross and a flat with a large diameter cylindrical structure. A
sensitivity analysis shows that due to the large amount of magnets, the
cross-shaped isolator is less sensitive to manufacturing tolerances.

Abstract

This paper focuses on the design and control of an active suspension
system, where a tubular linear motor is integrated into a spring damper
system of a vehicle. The spring takes up the weight of the vehicle.
Therefore the electric linear motor can be designed very compact as it has
to provide forces to adjust the damping characteristic only. Design and
construction of the active suspension system, a control strategy and
validation measurements at a test bench are presented.

Abstract

The drive train of a small scale magnetically levitated train reveals the
principles of a mechatronic system and offers challenges related to
design, construction and control. Therefore, it is used at the Institute
of electrical Machines (IEM) of the RWTH Aachen University as a
demonstrator for engineering solutions. Instead of being a part of a
static predefined student laboratory, the small scale magnetically
levitated train is part of dynamic individual student projects. This
approach provides the advantage that the students are directly involved in
the engineering process and gain motivation out of their personal ideas
becoming reality.

Abstract

This paper describes multiple electric field control methods for foil
coils in high-voltage coreless linear actuators and their sensitivity to
misalignment. The investigated field control methods consist of resistive,
refractive, capacitive and geometrical solutions for mitigating electric
stress at edges and corners of foil coils. These field control methods are
evaluated using 2-D boundary element and finite element methods. A
comparison is presented between the field control methods and their
ability to mitigate electric stress in coreless linear actuators.
Furthermore, the sensitivity to misalignment of the field control methods
is investigated.

Abstract

In intra-enterprise logistics and automation of manufacturing processes
general a rising productivity by high flexibility is required. Existing
transportation systems exclusively use two-dimensional track sections,
because they can be served with standard drives. Because of these simple
structures the transport speed is limited and thereby also the throughput.
In this paper now a modular transportation system is presented which could
reach higher speeds with a direct drive and the use of centrifugal force
compensating curves. Simultaneously the system also can change the
altitude. All this succeeds with the integration of three-dimensional
track sections. Therefore a two piped guiding system with a long stator
linear motor was designed. To combine the linear motor with the three
dimensional track special stator elements were developed which allow a
bending of the stator to follow the route course. The current work deals
with the implementation of a mechanical passive switch, which is operated
by the electromagnetic forces of the linear motor. So no additional
mechanical actors or a separate electromagnetic system are necessary.

Abstract

This paper evaluates the performance of fractional-slot per pole winding
configurations for tubular permanent magnet (PM) machines that can
effectively eliminate the most undesirable space harmonics in a simple and
cost-effective manner. The benefits of the proposed machine topology
winding configurations are illustrated through comparison with 9-slot,
10-pole tubular PM machine developed for a free piston energy converter
under the same specification and volumetric constraints. It has been shown
that the proposed machine topology results in more than 7 times reduction
in the eddy current loss in the mover magnets and supporting tube, and
hence avoids potential problem of excessive mover temperature and risk of
demagnetization.

Abstract

The car access time is a key parameter, especially in a huge
stereo-garage, where this one should be decreased as much as possible.
This paper proposes a novel stereo-garage. Adopting the linear induction
motors (LIMs), the system has a simple structure and rapid response
capability. In the stereo-garage, several LIMs are installed below the
crossbeam on a lifting platform, and several LIMs are fixed on the top of
a moving frame. During the operation of LIMs, the moving frame moves
forward and backward to reach the required parking place, whereas the
crossbeam moves horizontally in order to take or store the vehicle
rapidly. All these LIMs are the same and should be designed at a low
frequency. The influences of key structure parameters and dynamic
performances are investigated, based on FEM. The predicted results are
validated by a prototype. Finally, the designed LIMs are successfully
applied in two 8-layer stereo-garages.
